From b30c1a464c29baf646a5726d90ea3537e775ac85 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 28 Apr 2020 23:29:11 +0200 Subject: [PATCH] watchdog: iTCO: fix link error When the MFD driver is a loadable module, the watchdog driver fails to get linked into the kernel: drivers/watchdog/iTCO_wdt.o: In function `update_no_reboot_bit_pmc': iTCO_wdt.c:(.text+0x54f): undefined reference to `intel_pmc_gcr_update' The code is written to support operation without the MFD driver, so add a Kconfig dependency that allows this, while disallowing the watchdog to be built-in when the MFD driver is a module.
